.To all whom it may concern;

Be it known that I, ALBERT D. FIELD, of New York, in-the county of New York and State of N ewYork, have invented certain new i enable others skilled in the art to which it ap pertains to make and use the same.

My invention relates to an improvement in extensible curtain-poles.

The objects of my present invention are tov provide a curtain-pole that may be extended at one or both ends and be adapted to lie in fixed brackets or be held in position by socket ends, and, further, to producea substantial as well as handsome device of the character indicated, constructing it so as to admit of rapid and continuous production by machinery, thus affording a durable and elegant article for the purpose designated at a low initial cost.

With the attainment of the above-named objects in View, my invention consists in certain features of construction and combinations of parts that will be hereinafter described, and. pointed out in the claims.

Referring to the drawings, making a part of this specification, Figure l .is a view of the curtain-pole with its bracket-lugs shown in connection with a fixed bracket. Fig. 2 represents the same style of pole .provided with a modified form of bracket-lug, which latter is made of wire,while the preferred form is constructed of sheet metal. Fig. 3 is a view in elevation of the curtainpole and attached parts to fit it for support at any desired length upon a pair of fixed brackets. similar view of one endof a curtain-pole that is adapted to be supported by socket-rings that engage the ends of the pole. View of thecenter slide-pipe or hollow rod, an attached centering guide -bl,ock in position on the rod, and a bracket-lug made of sheet metal, showing plan-of securing these pieces together. Fig. 6 is alongitudinal section of the curtain-pole, as shown in Fig. 1 Fig. 7 represents a longitudinal section of the curtain-pole shown in Fig. 2. Fig. 8 is a modified form of a pole-supporting bracket that is made of two pieces of wire.

Fig. 4 1s a;

Fig. 5 is a The curtain-pole complete is composed of a central section, A, and two sliding tubular sections, A, which are made-to fit upon the center-piece. The central portion,A, is made,

preferably, of wood in cylindrical form, and

has an axial perforation, a, made throughout I its length. The longitudinalholea is pro"- duced by boring a solid stick, or it may be made in the form of a half-circular groove intwo corresponding half-cylinders .that are afterward glued or otherwise attached together to form a round pole with alongitudinal axial hole in it.

- g In the hole a two extension-rods, C, arefitted to slide freely and extend at each end. This connection should be such as to avoid improper looseness. The rods 00 are preferably constructed of sheet metal, such as tin -plate, as tin-covered sheet-iron is not liable torust, and is preferred on this account. The hollow rods are made of the sheet metal by proper means, and upon one end of each extensionrod C a round block or short cylinder of wood, D, is secured, which are intended to form guideblocks to keep the outer ends of the rods 0 steady when they are pulled out to sufficiently,

extend the length of the pole.

The guideblocks D D are of a proper diameter to enter and fit neatly within the tubular sections A of the pole A and slide in contact with the interior surface of said sections. Each of thesections A is provided with a longitudinal slot, b, which extends nearly to each end of the section. Theslots are designed toreceive the bracket-lugs E, (shown in Fig. 5,) which aremade of sheet metal stamped out and folded together so as to produce clasps at their inner ends, that conform to the surface of the extension-rods 0, upon which they are mounted, and are secured in place'by cuttin'gtwo lips loose on three sides ata proper point on the cylindrical wall ofthe sheet-metal hollow exlow rods 0, outside of the ears 0, and are of such a relative length as to allow a short end of the rod to project beyond each block, the

'blocks being held firmly against the bracketlugs, which are in contact with the ears 0, by

spreading the sheet metal of the rodoutwardl y to act as rivet-heads. In a similar manner the wire bracket-lugs shown in Fig. 2 are secured in position upon the rods 0, when that form of lug is to be employed, to afford a means of attachment of the curtain-pole to the supporting-brackets. The wire bracket-lugs H have eyes turned on each end at right angles to each other, the larger eyes, H, being made to fit upon the rods 0, as above stated, while the smaller eyes, H that are turned up on the projecting ends of the wire brackets H, are intended to engage the pintles e formed on the supportingbrackets I. (See Fig. 7.) The bracket shown in Fig. 1 is preferably made of cast metal, and may be given any ornamental form desired. Itis essential, however, that the upper edge of its outwardly-proj ecting body be provided at proper points with the pintles e, and also be curved or bent at the outer end to afford a cradle or support for the body of the curtain-pole, as shown in Fig. 1.

rated at a suitable distance from their outer end to afford a means of engagement with the pintles e of the brackets I, as shown in Fig. 6. In case a cheaper form of supporting-bracket is preferred the style shown in Fig. 8 may be adopted.

The supporting-bracket J (see Fig. 8) is composed of a piece of wire,f, which has one end, 9, flattened and bent at an angle to the round body provided with a hole for accommodation of a screw to affix the bracket-foot in position to the window-casement. The opposite end,h,of the piece f is bent at about the same angle as the lower end, 9, and in an opposite direct-ion.

A straight piece of wire K is flattened to produce a rounded outer end, i, that is perforated to be placed over the upper free end, h,

of the piece f, and as the opposite end of the straight piece K is threaded to produce a gimlet-pointed screw thereon, if the piece K is first screwed into the window-frame at right angles to it and the end 71. of the piecef inserted through the perforated outer end, i, and the lower end of f secured by screwing it fast to the frame by its lower end, 9, it will be seen that the piece f will form a diagonal brace to the projecting round wire rod K to give it stability sufficient to carry the curtain-pole and attached drapery, the bracket lugs or eyes of the pole being placed upon the upwardlyprojecting ends h of the wire brackets H.

When it is preferred or the situation requires that the curtain-poles should be supported in place without the use of the brackets such as have been previously described,

the poles may be held in position by the sockets or cupped flanges L, (see Fig. 4,) which are preferably cut and stamped into form by dies from sheet metal, and have perforated centers to receive the ends of the curtain-pole,

these annular cupped flanges having spaced screw-holes made near their peripheral edges to receive screws, by which they are attached in proper position to opposite points on the window-easements.

In case the curtain-pole is to be supported in place by the socket-flanges L, or be simply laid on the cast-brackets previously described, the bracket-lugs may be dispensed with and thetubular sections A ofthe pole be held in sliding connection with the center portion, A, by set-screws m,'which are inserted through the longitudinal slots formed in the sheetmetal sections A into the wooden piece A.

In the construction of the improved pole and brackets herein shown two extension'rods, C, may be employed to afford a means of ad j usting the length of the pole to suit the varying width s of windows, or the adjustment forlength may be made at one end only and but one extension-rod used.

If a great range of adjustment is required, this can best be afforded by the use of an adjusting device at each end of the pole.

When the poles are mounted upon brackets, their ends may be given an ornamental finish by the adjustment upon them of the globular ornaments shown, these spheres being preferably struck up out of sheet metal in two pieces, which are joined at their edges, and the globes secured to a socket that affords a means of attachment to the ends of the poles.

- Hard wood is preferred from which to construct the central portion of the curtain-poles, and this may be stained and finished in any style desired,or the wood may be covered with plush of any preferred color to match curtains, and thus produce beautiful efi'ects ata moderate cost. The metal portions are preferably made of sheet-brass which is lacquered to give it a rich golden appearance and prevent tarnishing of the bright metallic surface of these portions of the device. The brackets'may also be gilded or bronzed to render them harmonious in finish with the other portions of the metal work or trimmings of the curtain-pole.

I do not desire herein to broadly claim the use of a wooden center-piece and tubular end sections that slide on it, as I have already shown a method of construction of a solid pole and sliding sections in patent of record number 277,258, dated May 8, 1883; but,

Having fully describedmy invention, what I claim as new, and desire to secure by Letters Patent, is
